Why is the melting temperature of solid materials important to fire investigators?

The melting temperature of solid materials is important to fire investigators because it helps determine the severity of the fire. Understanding the melting point allows investigators to assess the conditions that the material was subjected to during the fire, including the temperature reached. Higher temperatures may indicate a more severe fire, while lower melting temperatures can suggest a less intense fire. This information is crucial in piecing together the events leading up to and during the fire incident, as it can provide insights into the heat source and the materials involved in the fire. Additionally, knowing which materials melted can help in identifying the characteristics of the fire and its potential causes.
